Got multiple I²C sensors with the same address? The Qwiic Mux Breakout uses the TCA9548A multiplexer to let them all communicate on the same bus. Select between eight downstream I²C channels, each isolated so address conflicts are eliminated.

The mux itself has eight configurable addresses via three solder jumpers, allowing up to 64 I²C buses when daisy-chaining multiple boards. Operating from 1.65 V to 5.5 V, it's compatible with both 3.3 V and 5 V systems. Qwiic connectors on every port make wiring fast and error-free.

Key Features

• 8-Channel I²C Multiplexer – TCA9548A allows eight separate I²C buses
• Address Conflict Resolution – Use multiple sensors with the same address simultaneously
• 8 Configurable Addresses – Three ADR solder jumpers for daisy-chaining multiple mux boards
• Wide Voltage Range – 1.65 V to 5.5 V operation
• Qwiic Connectors – Polarised 4-pin JST connectors on all ports for plug-and-play wiring

Ideal For

• Multi-sensor projects with I²C address conflicts
• Environmental monitoring with arrays of identical sensors
• Robotics with multiple distance or IMU sensors
